SOUTH-AFEICAN BUTTERFLIES. 
February 1867 ; it was flying pretty actively in a wood at the Umhlanga, and 
was netted by the late Mr. M. J. M'Ken, with whom I was on a collecting 
excursion. Mr. W. Morant lent me in 1869, for description, a ^ captured 
near Pinetown, and Colonel Bowkcr sent a perfect specimen of the same sex 
taken by him in that locality in June 1884, as well as a pair which he took 
nearer D'Urban in 1881. Single examples have also reached me from Maritz- 
burg and St. Lucia Bay, as well as three forwarded from Delagoa Bay by Mrs. 
Monteiro. Moschler {Verh. K.K. Zool-Bot. GesellscJi. Wien, 1883, p. 10) 
notes the receipt of a ? from Baziya, east of the Bashee River in Kaffraria 
Proper ; and this is the southern limit of the range of the insect, as far as I 
can discover. It is not improbable that Thysa is less rare than it appears to 
be, as it might very often be passed over by collectors as the common M.

1 No fewer than eleven specimens have been sent to me by Mr. A. D. Millar, who took 
them in the vicinity of D'Urban, Natal. From the dates of capture kindly furnished by 
Mr. Millar, I find that nine of these (six 6 s, three 9 s) were taken in August and Sep- 
tember 1887 ; they are all smaller than usual, and have the hind-marginal black markings 
decidedly reduced. The remaining two are a pair taken in cojmld on the 29th January 
1888 ; they are of large size, and both (but more especially the ? ) have the hind-marginal 
markings strongly developed. The ? , indeed, has these markings (more particularly in 
the hind-wings) larger and more extended inwardly than in any other example that I have 
seen ; her fore-wings are almost pure white on the disc, but the reddish basal suffusion is 
densely clouded with grey, and there is a separate patch of grey scales near posterior angle. 
I suspect that the larger and more strongly marked specimens represent what is the 
summer or wet-season brood. The ? that I took in February was also very large, and had 
the dark markings much developed.
